7 Claims, 9 Drawing Figures PATEWEDAPR 18 m2 SHEET 1 [1F 3 IN VEN TOR W PNENTEDAPR 18 I972 SHEET 3 BF 3 IN VE N TOR TILTING TABLE The present invention relates to a folding table with at least two table-tops disposed one on top of the other, which are hingedly connected on four columns disposed in the edges of the table-tops and in which each table-top consists of two tabletop halves tiltable relative to each other such, that top consists of two table-top halves tiltable relative to each other such, that the folding axle of the table-top halves extends in a plane between the columns.
The known structures of such tables have the extreme drawback of a more difficult accessibility from the sides, at which the means making possible the space-saving collapse or folding are arranged. The manipulation or operation for bringing about the space-saving folded position is difficult, and due to the practically freely disposed guides so not entirely without danger. In addition the guide members assume merely optically extensive weight.
It is one object of the present invention, to provide a folding table, wherein the table of this type is made of the least possible, simple structural parts, which table beyond that is simplified in its operation, has furthermore a better accessibility and finally also has an appealing outer appearance.
It is another object of the present invention, to provide a folding table, wherein a coupling rod is provided connecting the upper table-top halve with the lower table-top half, which coupling rod extends in the plane of the pivot axles of tabletop halves, preferably in central position of the table-top.
It is in accordance with the present invention of advantage thereby, if the bolt of the pivot axle has at both ends oppositely thereof a resilient gripping handle, which has engagement faces for the counter-faces on both table-top halves.
A favorable feature of the present invention resides in the fact, that the table-top has frame members and the gripping handle has corresponding recesses.
In accordance with the present invention, it is also favorable, if each of the two table-top halves is pivotally connected at a horizontal rail, which connects two vertical columns equipped with running rollers at the height of the table-top and that these columns are connected likewise by means of a horizontal second rail in the vicinity of the lower end.
The present invention proposes furthermore, that the rail has the form of a rod of round cross-section, the end of the table-top halves pivoted to the end overlaps the table-top half with a groove, in which on the other side of the rail a holding part is retained by means of a groove and tongue.
In accordance with the present invention, it is another object of the present invention, that the coupling rod engages in the center of the folding axles. It is also advantageous, in accordance with the present invention, if all table-top-halves are equal relative to each other and the frame members widen themselves to the column side end.
Beyond that, it is favorable in accordance with the present invention, if the frame members abut in use position of the table-top against abutments of the columns, whereby the abutments have preferably entrance grooves for the frame members.
Also the present invention brings about the proposal that pivotal axis is disposed in low-sided rails of the table-top halves.
Finally it is in accordance with the present invention of advantage, that the coupling rod with its lower extended end projects down to the floor.
Finally also a favorable feature of the present invention resides in the fact, that all the columns and the coupling rod are equipped with running rollers or rolling gears.
Due to such arrangement a foldable table of increased use value is created. Its operation or handling is simple and not dangerous. The supporting face of the lower table-top halves is freely accessible from all sides for reasons of a central arrangement of the coupling rod. This coupling rod has optically no weight. It fulfils a double fimction: First it connects together the folding axles of both table-top steps and in addition it brings about a central support due to the extension of its bottom-sided section up to the supporting floor. By this arrangement an extremely load-capable structure is achieved. For folding of the table is merely required, to pull away the handle grips against the effect of the spring from the counterfaces on the two table-top halves and to lift lightly the table in this position. By this arrangement the table-top halves fold automatically by their own weight into the folding position. The use position can likewise be equally easily brought about, by merely spreading the table columns. The grips enter swingingly again into the safety position. The hinge for the table-top halves is formed by a horizontal rail connecting the columns any way with each other. The corresponding structure of the present invention is set entirely to a simplified mounting. Concerning the structure of the table-top halves, by completely equal formation of these halves, account is taken with the requirements concerning a mass production. A use position is defined by abutment on the columns, while the grip constitutes substantially merely a safety of this position, thus isto a great extent free of loads. The structural arrangement, to permit entrance of the frame members of the table-top halves in grooves of these abutments, brings about simultaneously a side stabilization, particularly since the frame members are widened within the range of the columns. The arrangement of running rollers, particularly of steering rollers, at the columns and even on the downwardly extending coupling rod, permits to move the folding table even in its loaded state.
With these and other objects in view, which will become apparent in the following detailed description, the present invention, which is shown by example only, will be clearly understood in connection with the accompanying drawings, in which:
FIG. 1 is a perspective view of the folding table in accordance with the present invention and in particular in use position;
FIG. 2 is a side elevation of the collapsed folding table and in particular in a space-saving collapsed position;
FIG. 3 is a perspective view of a pair of columns with the rails connecting the same in the parts for the pivot connection of the table-top halves;
FIG. 4 is a section of the pivot point;
FIG. 5 is a longitudinal section within the range of the pivot axle with a right-sided removed handle grip and a left-sided handle grip disposed in safety position;
FIG. 6 is a section along the lines 6 6 of FIG. 5;
FIG. 7 is a perspective view of a second embodiment of the folding table;
FIG. 8 is a fragmentary section indicating the possibility of the guiding roller arrangement on the coupling rod; and
FIG. 9 is a variation of the showing in FIG. 8.
Referring now to the drawings, the folding table designed in accordance with the present invention has four vertical columns la, 1b, 1c and 1a, which are equipped at their lower edge with a running roller 2.
The two columns la and lb are connected by the use of round rods, namely an upper round rod 3 and a lower round rod 4 to form a stifi rail.
In the same manner the columns 1c and 1d are also formed by such round rods to a rigid frame. The round rods are disposed horizontally. The upper round rods 3 serve as rotary pivot pins for the table- top halves 5 and 6, the lower round rods 4 as rotating pins for the table- top halves 7 and 8, forming the second table-top.
The table- top halves 5 and 6 are completely equally formed relative to each other.
Also the column-sided pivot formation is equal in all tabletop halves. For this reason only one pivot pin is shown in the drawing, namely that of the tabletop half 5. The latter has on both of its longitudinal sides a frame 5b, which widens in outward direction, that means towards the column end continuously downwardly, in order to continue finally into a wall 5f extending perpendicularly thereto. A hook-shaped part 5a 1 continues from the wall 5f. The part 5a is of lower height than the wall 5f.
On the inner side of the hook-shaped part a projecting over the entire width of the table-top half 5 and on the outside of the wall 5f extending likewise of the entire width of the table-top half 5 are provided oppositely disposed grooves 15. For the formation of the bearing recess, a rail 14 is pressed in form below into the space between the parts 5a and 5f, so that their longitudinal ribs 14a enter the grooves 15. The rail 14 has at its center a projection 14b, which engages from below the round rod 3, which is thus retained from below and from both sides by the rail 14 and from above by the table-top half 5.
An abutment 16 disposed at the column 1a and under circumstances on all columns limits the outward swinging of the table-top halves such, that the frame member 5b enters the groove 16a. The frame member 5b and under circumstances all frames are thus stabilized in lateral direction.
The table- top halves 5 and 6 run towards the center of the table in a plurality of sleeves 5c, 6c, respectively, which are spaced from each other, which space is of the same length as the length of the sleeve, of course with the provision of a certain play.
Perpendicularly above the axle of these sleeves 5c terminates the plates 5 and 6 terminate with a vertical rail 5e and 6e, respectively.
A pivot bolt 9 is inserted (FIG. 5) into the sleeves 5c of the table-top half 5 and the similarly-formed sleeves 6c of the table-top half 6,
Due to the vertical rails 5e and 6e of the table- top halves 5 and 6, as of course also of the lower table-top halves, these table-top halves can be turned about the round rods 3 downwardly only up into the horizontal position. Upwardly, the table- top halves 5 and 6 and the round rod 3 can swing so far, until their frame members 5b and 6b engage each other (FIG. 2). The frames have thus a height, which assures a certain distance of the columns relative to each other in the folded position, whereby the standing ability is retained also in folded position.
The pivot axle bolts 9 have at both ends an angular groove 9a, in which a spring ring 24 sits, which prevents an axial movement of the table- top halves 5 and 6 relative to the bolt 9. The two outer ends of the bolt 9 are equipped with a thread 9b, on which a nut 12 is screwed on, which carries in an annular slot 120 a spring 23. The spring 23 supports itself, on the other hand, on a handle or manual grip 11, which has a recess 110 for the spring ring on the side pointing towards the tabletop halves. Furthermore, the handle grip 11 has an inwardly projecting upper rail 11a and a likewise projecting however slightly shorter lower rail 11b. The lower edge of the upper rail 11a is disposed closely above the surface of the table-top halves 5 and 6 (FIG. 6), while the upper edge of the lower rail 11b is closely below the lower edges of the frame members 5b and 6b. The handle grips 11 are displaced by the springs 23 such, over the median part of the side edges of the table- top halves 5 and 6, that the table- top halves 5 and 6 are assured in an exactly horizontal plane, which is flush with each other. Between the rails 11a and the the recess 110, the manual grips include abutment faces lid for outer counter faces 11e disposed on lateral ends of the tabletop halves 5 and 6.
The lower plane halves 7 and 8 are connected together in similar manner by a pivot axle bolt. The pivot axle bolt 13 and the pivot axle bolts 9 are connected together by means of a vertical coupling rod 10 extending in the plane of the first axles. This coupling rod sits in an overall distance from the side edge of the table-top halves and in particular in central position of the table-top halves.
The coupling rod has for its pivotal connection to the mentioned bolt at its upper end and within the range of the lower end an eye formation, through which the bolts 9 and the bolts 13, respectively, are guided through.
If the table in upright position, as shown in FIG. 1, is to be folded up, one pulls on the two handle grips 11 in opposite directions until the lower projection is outside of the range of the frame members of the table- top halves 5 and 6. This position is shown on the right side of FIG. 5, while on the left side of this Figure the position is shown, which the handle grip 11 assumes in use position of the table. After both handle grips 11 have been pulled outwardly, by upward drawing of these two handle grips, the table can be folded or collapsed without difficulty into the shape shown in FIG. 2. The table- top halves 5 and 6 are equipped with reinforcement ribs 6d and 5d, respectively, (FIG. 6), where they are no more reinforced, by narrow frame members.
The folding table, in accordance with the second embodiment, is completely equally formed with the exception of the coupling rod 10 of the previously described example or embodiment. For this reason the same numerals have been applied in the second embodiment.
In a further development of the first embodiment, the rod 10 is extended downwardly as an integral member 17, which has a running roller 18 and is extended such, that the running roller 18 is disposed in the same plane as the running rollers 2.
The parts 10 and 17 can be formed integrally. The arrangement can be made, however, also such and this is particularly of importance for a later equipment with a running and pivot roller 18, respectively, that the coupling rod 10 is disposed below its bore, with which it grips or surrounds the pivotal axle bolt 13, has a threaded bore 10b, while the member equipped with the running roller 18 has a corresponding threaded bore 17b (FIG. 9). Instead such screw connection also the possibility exists, that a plug connection is provided, as it is shown in FIG. 8. Here the coupling rod 10 has below the bore for the hinge bolt 13 a projection 10a with a circular bore with a groove 10d, while the part 17 has a projection 17c corresponding with the bore 10c and an annular groove corresponding with the annular groove 10d, the latter serving the mounting of a spring ring 28, which maintains the plug connection.
Instead of providing two pairs of table- top halves 5, 6, 7 and 8, more plates can be disposed on top of each other and can be connected by a correspondingly extended coupling rod 10.
